Haglund’s Deformity Symptoms, Causes, and Treatment

It started as a small bump at the back of your heel that you only noticed when slipping into your work shoes. Over months and years, the bump became more visible. The skin over it has started to redden and sometimes blister where the shoe rubs. The area is tender to the touch. Wearing your usual dress shoes or pumps for a full day is now a daily negotiation between style and tolerable pain. You have tried different pairs, gel pads, and even cutting open the back of older shoes. Some help a little. None of them resolves it. The bump is still there, and the inflammation around it keeps returning.

This is what patients usually tell us when they are dealing with Haglund’s deformity, sometimes called pump bump because it commonly worsens with rigid-backed shoes including dress shoes and high heels. The condition involves a bony enlargement at the back of the heel bone, the calcaneus, where the Achilles tendon attaches. When the bony prominence is repeatedly pressed against the rigid back of a shoe, the soft tissue between the bone and the shoe, including the retrocalcaneal bursa, becomes inflamed. Haglund’s deformity is a structural condition, so the underlying bony prominence does not reduce in size with conservative treatment. The aim of management is therefore to settle the inflammation, redistribute pressure away from the area, and prevent the cycle of irritation that turns a manageable bump into chronic heel pain.

Symptoms of Haglund’s Deformity

Unlike what the internet says, Haglund’s deformity itself is painless. However, the presence of the bump creates irritation on the surrounding tissues, which leads to pain and discomfort. Symptoms develop gradually over months in most cases, often becoming progressively more noticeable as the bump enlarges or as repeated shoe pressure inflames the surrounding tissue. A smaller proportion of patients describe a more sudden onset, typically triggered by a recent change in footwear or a sudden increase in activity.

• Visible bony bump at the back of the heel a firm, fixed prominence at the upper outer aspect of the heel, just above where the Achilles tendon meets the bone. The bump itself is bone, not soft tissue, so it does not move or compress under pressure.
• Pain at the back of the heel, especially with shoes sharp or aching discomfort that worsens when wearing shoes with rigid heel counters such as dress shoes, pumps, hiking boots, or some athletic shoes. Pain tends to ease when barefoot or in open-backed footwear.
• Redness and swelling over the bump the skin and soft tissue overlying the bony prominence often becomes inflamed, with visible redness, warmth, and sometimes swelling that can be felt.
• Blistering or callus formation at the bump site repeated friction between the shoe and the prominence often produces blisters or a thickened callus, particularly at the upper outer edge.
• Tenderness on direct pressure pressing the bump from behind reproduces the pain, often more on the outer aspect than the centre.
• Achilles area stiffness or pain because the deformity sits close to the Achilles tendon insertion, many patients also notice stiffness in the back of the heel, particularly on the first few steps after rest, similar to insertional Achilles tendonitis.
• Both heels affected, often asymmetrically many patients have the deformity on both sides, though typically one side is more symptomatic than the other.

Causes of Haglund’s Deformity

Haglund’s deformity has both anatomical and external contributors. In most cases, a combination of factors produces the bony enlargement and the surrounding tissue irritation.

What Causes Haglund’s Deformity?

• Inherited heel bone shape the most consistent factor is the underlying shape of the calcaneus. A naturally high posterosuperior prominence (the upper back portion of the heel bone) creates the bony bump and predisposes the area to irritation when in contact with shoe backs.
• High-arched feet (pes cavus) patients with high arches sit differently inside the shoe, pushing the back of the heel against the heel counter with each step.
• Rigid heel counters in footwear dress shoes, pumps, hiking boots, and certain athletic shoes have stiff backs that press directly against the bony prominence. Repeated pressure produces inflammation in the surrounding soft tissue.
• Tight Achilles tendon and calf muscles reduced ankle dorsiflexion increases tension at the Achilles insertion, which sits immediately adjacent to the bony bump, contributing to chronic irritation.
• Inward-rolling gait pattern (overpronation) although Haglund’s deformity is more associated with high-arched feet, abnormal gait mechanics can shift load through the back of the heel and accelerate irritation.
• Repeated heel impact from running or sport high-volume running, particularly on hard surfaces in shoes with rigid heel counters, increases mechanical load at the area.

Who Carries a Higher Baseline Risk?

• Adults aged 20 to 50, when the condition is most often first noticed clinically, though the bony anatomy is usually present at skeletal maturity
• Women who regularly wear pumps, high heels, or dress shoes with rigid heel counters for work
• Men in professional roles who wear stiff-backed dress shoes daily
• Runners with high training volume, particularly on hard surfaces and in racing shoes with firm heel counters
• People with high-arched feet or naturally prominent posterior heel bones, often present bilaterally
• Patients with tight Achilles tendons or limited ankle dorsiflexion
• Those with a family history of similar heel prominences, since the bony shape tends to be inherited

Conditions Commonly Mistaken for Haglund’s Deformity

Two conditions are often mistaken for Haglund’s deformity, and a third often coexists with it. Distinguishing between them matters because their management approaches differ.

Insertional Achilles tendonitis

Both conditions produce pain at the back of the heel, both worsen with activity, and both can produce stiffness on the first few steps after rest. The distinction is anatomical. Insertional Achilles tendinopathy involves the tendon itself at the point where it attaches to the heel bone, with tenderness directly at the tendon insertion. Haglund’s deformity involves the bony prominence above the tendon, with tenderness at the upper outer heel. The two conditions frequently coexist as part of Haglund’s syndrome, and clinical examination is needed to identify which is the dominant source of symptoms.

Posterior heel spur (calcaneal spur)

A heel spur is a bony outgrowth that forms at a point of tendon attachment, typically as a response to chronic traction on the bone. A Haglund’s deformity is a different anatomical feature: a naturally enlarged or prominent upper-back portion of the heel bone that does not result from tendon pulling. The pain mechanisms differ. A posterior heel spur tends to produce sharp pain directly at the Achilles insertion. Haglund’s deformity tends to produce pain over the bony prominence itself, especially with shoe contact.

Retrocalcaneal bursitis

Retrocalcaneal bursitis is inflammation of the small fluid-filled sac (bursa) that sits between the back of the heel bone and the Achilles tendon. It very often develops as part of Haglund’s syndrome, triggered by the bony prominence pressing against the bursa and irritating it. Pure bursitis without a bony prominence can occur, particularly after a single traumatic event, but in most cases bursitis and Haglund’s deformity travel together. Settling the bursitis is part of managing Haglund’s deformity, not a separate condition.

Treating and Preventing Haglund’s Deformity

The bony prominence at the back of the heel is structural, so conservative treatment does not reduce the bump in size. What it does, and does effectively in most cases, is settle the inflammation in the surrounding tissue, redistribute pressure away from the area, and break the cycle of irritation that produces the pain. The single most important lever is footwear, because no amount of padding or therapy holds if the same rigid-backed shoes keep pressing on the bump all day.

Conservative treatment

Conservative care pairs footwear and offloading changes with measures that calm the inflamed soft tissue and reduce the load reaching the back of the heel.

• Footwear modification: Switch to open-backed or soft, flexible heel counters during flares and for daily wear, and add heel lifts inside closed-back shoes to raise the heel above the point where the bump contacts the shoe. Avoid rigid heel counters such as dress shoes, pumps, and stiff athletic shoes while the area is irritated.
• Padding and offloading: Soft heel pads, silicone heel sleeves, or felt padding placed directly over the bump cushion contact with whatever footwear is unavoidable.
• Cold therapy and anti-inflammatory measures: Ice applied for 15 to 20 minutes two to three times daily in the first 5 to 7 days, with anti-inflammatory measures as advised by a healthcare provider where appropriate.
• Calf and Achilles stretching: Consistent stretching reduces tension at the Achilles insertion, which sits immediately next to the bony prominence.
• Custom foot orthotics: Orthotics with appropriate heel cushioning and arch support redistribute load away from the back of the heel, and are particularly useful where high arches contribute to the load pattern. Addressing biomechanical factors such as limited ankle dorsiflexion or gait abnormalities is part of the same picture.
• Focused shockwave therapy and EMTT: Where the retrocalcaneal bursa or Achilles insertion has become chronically inflamed despite consistent conservative care, shockwave and radial pressure wave therapy can support tissue remodelling, and extracorporeal magnetotransduction therapy may be considered for selected cases. These do not change the bony shape but can improve the soft tissue picture around it.

When conservative care isn’t enough

Surgery is usually reserved for cases that have not responded to 6 to 12 months of structured conservative treatment. Surgical options typically involve removal of the bony prominence, debridement of the retrocalcaneal bursa, and where needed, repair of the Achilles tendon. That decision is made together with an orthopaedic foot and ankle surgeon after conservative care has been genuinely exhausted, and a referral is arranged where it becomes necessary.
